Answer: $x=-1$

Step-by-step explanation:

By the negative exponent rule, you have that:

$(\frac{1}{a})^n=a^{-n}$

By the exponents properties, you know that:

$(m^n)^l=m^{(nl)}$

Therefore, you can rewrite the left side of the equation has following:

$(\frac{1}{8})^{-(2x+7)}=(\frac{1}{32})^{3x}$

Descompose 32 and 8 into its prime factors:

$32=2*2*2*2*2=2^5\\8=2*2*2=2^3$

Rewrite:

$(\frac{1}{2^3})^{-(2x+7)}=(\frac{1}{2^5})^{3x}$

Then:

$(\frac{1}{2})^{-3(2x+7)}=(\frac{1}{2})^{5(3x)}$

As the base are equal, then:

$-3(2x+7)=5(3x)$

Solve for x:

$-6x-21=15x\\-21=15x+6x\\-21=21x\\x=-1$

Find a close estimate for square root of 45. (without a calculator) Round your answer two decimal places

dusya [7]

You know that 7*7 is 49, and 6*6 is 36. Now you know it will be 6._. 6*7 is 42, so think of that as 6.5^2. You know that it will most likely be less than 6.8 since it is so close to being 7*7, which is 4 above your desired number. This leaves 6.6 to 6.8 as your estimate. Personally, I would go straight in the middle and choose 6.7.

I hope this helps!

Answer:

$Probability = \frac{1}{6}$

Step-by-step explanation:

Given

The above table

Required

Determine the probability of a sum that is a multiple of 6

Represent the event that an outcome is a multiple of 6 with M.

List out all possible values of M

$M = \{6,6,6,6,6,12\}$

Number of M is

$n(M) = 6$

Total possible outcome is:

$n(Total) = 36$

The theoretical probability is then calculated as follows:

$Probability = \frac{Number\ of\ desired\ outcomes}{Number\ of\ possible\ outcomes}$

In this case, it is:

$Probability = \frac{n(M)}{n(Total)}$

$Probability = \frac{6}{36}$

Simplify fraction

$Probability = \frac{1}{6}$

The circus is coming to town. Cindy is selling tickets. The first day she sold 8 adult tickets and 5 children tickets for a tota

Galina-37 [17]

Let the price of adult ticket and children ticket be a and c respectively
8a+5c=177.50 -> 24a+15c=532.5
12a+6c=255.00 -> 24a+12c=510

24a+15c-24a-12c=532.5-510
3c=22.5
c=7.5
a=17.5
